Could there be some timing/performance issue causing those failures?

It's possible.  We try to not make the tests timing-sensitive where
possible but some of them are inherently racy.

The slowest machine I've run the tests on is either a 166MHz powerpc
or a 170 MHz sparc.  On the sparcs at least, building openssl with gcc
-mv8 or better makes a huge difference because it enables the hardware
multiply, and DH does a lot of multiplies.


Good call.

I rebuilt openssl with sparcv8 on the Solaris 7 host, and now it can complete the rekey test. I guess there is a timeout somewhere that causes the test to fail if it takes too long to do the math. I'm not sure I can get much more performance out of the IRIX 5.3 host, so if there is a way to avoid or extend this timeout that would be nice.

-tgc
